500 error

[Skodaforum]

Startet getting e-mail from cron tab, whole site is down now:

When I try to enter the admin area I get the following message:

We're sorry, but a temporary technical error has occurred which means we cannot display this site right now. Can't create more than max_prepared_stmt_count statements (current value: 16382)You can try again by clicking the button below, or try again later. 

Any clue? Is there someway to "restart" the software, clear cache or well...anything I can do..

Tried to restart server...no luck.

This is from the server error log:

Tried now.

Only the error page changed. Still 500 though

I'd have to suggest a ticket in the Client Area

I do have a *slight* suspicion this is actually a server side / mysql concern however the support tech will be able to tell you if you need to speak to your host if its something not IPS software related as such.

Resolved.

Restart of mysql did the trick.

Got no clue what caused the problem though
